Caution - Do not attach power cords to the power supplies on the compute nodes until you have connected the compute nodes to a serial terminal or a terminal emulator (PC or workstation). The compute nodes go into Standby mode and Oracle ILOM on the SP initializes as soon as power cables connect the power supplies to an external power source. System messages might be lost after 60 seconds if a terminal or terminal emulator is not connected to the SER MGT ports before power is applied. |
Provide a suitable power source with electrical overload protection to meet the power supply input voltage range of 100 to 240 VAC, 50 to 60 Hz. The storage arrays are compatible with 100 to 120 VAC or 200 to 240 VAC sources. The power source must not be overloaded by the total number of storage arrays in the rack.
Ensure that the power source provides a reliable earth connection for each storage array and the rack.
Ensure that the power source is easily accessible because the power cord is the main disconnect device for the storage array.

When the power cords are connected, the SP initializes and the power supply LEDs illuminate. After a few minutes, the SP login prompt is displayed on the terminal device. At this time, the host is not initialized or powered on.
